Claims.

This invention relates to improvements in closures or stoppers forbottles and other containers, wherein a compressible member is providedwith a knob for facilitating the insertion into and re- 5 moval of theclosure from a container.

In the closures or stoppers herein disclosed, a compressible member,such as a cork or soft rubber plug, is provided with a knob which may bemade of a single piece of sheet material or which may consist of twointerlocking shells, which are shaped to form an outer and an innerwall. The inner wall of the knob preferably has protruding partsoompressingly gripping or biting the circumferential surface of thecompressible member.

The stoppers or closures of this type now in existence are eitherinefficient or expensive to manufacture. The present invention aims toprovide efficient closures for containers, that can be cheaply stampedout of sheet material.

.20 It is an object of the present invention to provide a closurecomprising a combined cap and compressible member in which the cap hasan outer shell and an inner shell, the inner shell having twoconcentrically-arranged spaced-an- ,2 5 nular portions inner and outer,respectively, with a disc integrally united to the inner annular portionat its top, the member being held at its circumferential wall within theinner annular portion; the outer shell having a disc portion overlyingthe upper edges of the inner and outer annular portions of the innershell, and a skirt portion overlying the flange of the inner shell.

It is a further object of the present invention to provide a closurecomprising a combined cap and compressible member, the cap including ashell having two concentrically-arranged spacedannular portions innerand outer, respectively, the said portions being connected at theirbottoms by a flange, and a disc united to the inner .40 annular portionat its top, the member being held having an anti-slip contact wall forfixedly engaging the compressible member.

The foregoing and other features of the invention will become moreclearly apparent from the following description, which is descriptive ofthe 5 preferred embodiments of the invention illustrated in theaccompanying drawing. However, the embodiments herein shown anddescribed being for purposes of illustration only, it is to beunderstood that such modifications may be made, 10 when desired, withinthe scope and spirit of the invention as claimed.

In the drawing Fig. 1 is a vertical sectional view of a closure, partlybroken. 15

Fig. 2 shows a sectional view of an embodiment of this invention, amodification of Fig. 1.

Fig. 3 shows another'modification in vertical cross section.

Fig. 4 representsa closure in section, an em- .20 bodiment of thisinvention having modified gripping means. E

Fig. 5 is a cross section of a closure, embodying this invention,wherein the knob or cap is made of a single piece of sheet material. 225

Figs. 6, '7 and 8 illustrate stoppers with knobs or caps having variousforms of finger grips.

Similar numerals and characters designate similar or. correspondingparts throughout the several views. 30

Referring to Fig. 1, character A designates a compressible member madeof cork, rubber or other suitable material in the form of a cylinder.This member A is secured to a cap which may comprise an inner shell Bandan outer shell C 35 in interlocking engagement. The inner shell B, whichis preferably made in the form of a metal stamping has the circularhollow centralportion [0 receiving the upper portion of the member A andbeing provided with teeth, corrugations or projections 9 biting into orgripping the Wall of the compressible member A. The rim portion of thiscap is flanged outwardly extending upward to form a circular wall llconcentric with W and around the portion l0 but preferably spacedtherefrom.

The outer shell C is cup-shaped and applie in inverted position.

The central portion of disc I2 may be depressed providing the recess Illand the annular rim'or" ridge Ill" abutting the underface M of circulartop [3. The circular top edge l3 of the outer wall ll of inner shell Balso abuts against the underface M of top 13, with the skirt 26 of capportion C in tight fit engagement with the circular wall I l of innermember B.

The shells B and C are firmly gripped together by turning in the rim l5of the outer shell C 5 which is received in the annular recess 25 andpresses against the annular shoulder I6 of the inner shell B.

In Fig. 2 the arrangement of the shells B'C' of the knob or cap issubstantially similar, though 10 not in detail to that shown in Fig. 1.In this construction, the disk portion l2 of the inner shell B iscompletely spaced from the underface M of the outer shell C, the outerwall ll accepting the burden of pressure in the interlocking of theshells. The rim l5 of the outer shell C is bent inwardly against theshoulder l6.

Fig. 3 shows the cap of Fig. 2 in a modified form, in which the rim l5"of the outer shell C is turned in to be flatly against the underface ofshoulder 16, the two shells being held in interlocking relation.

In Fig. 4, the cap is formed of a Single stamping presenting acup-shaped shell D having a skirt portion 21 terminating at its bottomin an inwardly bent shoulder or rim 28, the latter extending upwardlybreaking into a plurality of petallike teeth I! which terminate inpointed or substantially pointed ends IS. The cork or other compressiblecylinder A is forced against the somewhat yielding teeth I! into therecess 19 of the cap. The teeth portions 18 are inwardly bent orprojected so as to press againstand bite into the cork A thus insuring afirm grip. The upper or engaging end of the compressible member A restsagainst the recess bottom 20.

In Fig. 5, the container closure consists of a compressible member, suchas the cork A and a cap or knob D. The cup-shaped cap is made in onepiece of sheet metal, the rim of the cap being inwardly turned as at ZIIand then upwardly as at 22 into a loop, terminating at the underface 20of the cap and thus forming a circular recess, into which fits the corkA, and an annular air space 23. The inner annular wall 22 is pro videdwith a plurality of teeth or projections 9 as in Fig. l.

In Figs. 6, 7 and 8, which show side views of closures, having caps orknobs E, E, E provided with different gripping surfaces; Fig. 6 shows a5 polygonal knob; Fig. 7 a toothed knob and Fig.

8 a circular disked knob. These knobs may embody any of theconstructions shown in the preceding views.

In the drawing and description I have set forth cap or knob parts whichare preferably made of sheet metal, as they are believed to be thecheapest and simplest from a commercial standpoint. However, they may bemade of any other suitable material.

This application is in part a continuation of my copending applicationSer. No. 90,491 filed July 14, 1936.

From the foregoing description taken in connection with the accompanyingdrawing, it is 5 apparent that an improved simple, practical andinexpensive device for the purpose intended is provided. It is apparenthowever, that immaterial changes and modifications may be made byskilled persons without, departing from the 70 true spirit and scope ofthe invention as outpertinent prior art.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:
